By respectively setting electrodes 308 inside the key sleeve 301 and at the bottom end of the push plate 302, the push plate 302 can be pushed to move without using a key. Since there is no length limit for the key, the electrode 308 of the push plate 302 is connected to the electrode 308 inside the key sleeve 301, and then a signal is transmitted to the controller 601. The controller 601 starts the buzzer 602 to alarm.

When one corner of the push plate 302 is pushed, the push plate 302 will be tilted inside the key sleeve 301, and the lock cannot be opened. By arranging a sponge block 205 and the like on the surface of the fingerprint scanner 603, when it is necessary to scan the fingerprint, it is necessary to use a finger to push the push rod 204 to slide along the limiting slide rail 202.
